Answer:

x=-1 and x=3

Step-by-step explanation:

The zeroes of a function are its x-intercepts when the function passes through the x-axis. In this case, the parabola passes through (0,-1) and (0,3) which means the x-intercepts are x=-1 and x=3, which are also the zeroes.

Serggg [28]

A person eating at a cafeteria must choose 4 of the 13 vegetables on offer. calculate the number of elements in the sample space for this experiment.

Answer: The number of elements in the sample space for this experiment can be found using the combination formula because the order does not matter here.

Therefore, the number of elements in the sample space for this experiment is:

$13C4=\frac{13!}{(13-4)!4!}$

$=\frac{13!}{9! \times 4!}$

$=\frac{6227020800}{8709120}$

$=715$

Therefore, the number of elements in the sample space for this experiment is 715.

14/21
divide top and bottom by 7
2/3

26/39
divide top and bottom by 13
2/3

ss you can see now, the ratios are indeed equal, so they do form a proportion

Sladkaya [172]

The average price paid by him for the shares after 3 months is ksh. 163.33

<h3>Average</h3>

Total value of shares bought = ksh.20,000

Amount of shares bought in the first three months = ksh.120, ksh.160 and ksh.210

Average price paid for the shares after 3 months

= (120 + 160 + 210) / 3

= 490 / 3

= 163.333333333333

Approximately,
